Central retinal vein and artery occlusions related to intraocular involvement of an anaplastic optochiasmatic glioma

Malignant optic tract gliomas are very aggressive and extremely rare tumors progressing to blindness and death in a few months. We report here the case of a 73-year-old patient who presented a sudden decrease in visual acuity in his left eye associated with papil-ledema and headache: it revealed an optochiasmatic anaplastic glioma. A few months later, the glioma had grown, with infiltration of the right optic nerve and right peripapillary intraocular invasion. Through this case, we discuss the importance of achieving imaging for atypical optic neuropathies and stress the exceptional nature of intraocular invasion by a glioma. (C) 2010 Elsevier Masson SAS.
